Certain convergence estimates for the semi-exponential operators associated with 1 + x2 are established including weighted approximation, a direct result involving classical modulus of continuity and quantitative Voronovskaya-type theorem in weighted spaces. Initially, the moments are obtained following a recurrence relation for these operators and then some direct results are estimated.
